If I'm on starboard and I have my bow tucked behind the start boat and he is backing from in front of the start boat with water to go where ever he wants he must stay clear of me as does the rest of the fleet
There are two rules that bear on this situation. RRS 22.3 states "a boat moving astern through the water by backing a sail shall keep clear of one that is not". If the boat clear ahead is "backing a sail", then she must keep clear. If she is drifting backwards without backing a sail, then the other boat must keep clear (RRS 12).
Second, a boat's "course" is the direction she is pointing or moving. When the boat ahead stops moving forward and starts moving backward (without backing a sail), she is changing course and must give the boat astern room to keep clear (per RRS 16.1). That boat must react to the ahead boat's course change promptly and in a seamanlike way to keep clear.
